Daniel McCook (June 22, 1801 – July 21, 1863) was an American lawyer, politician, and Union Army officer during the [[American Civil War]]. He is best known as the patriarch of the famed "Fighting McCooks" of Ohio, a family that contributed fifteen officers to the Union cause, including himself, his eight sons, and five nephews.
Early Life and Career: Born in [[Canonsburg, Pennsylvania]], Daniel McCook moved to [[New Lisbon, Ohio]], as a child, and later settled in [[Carrollton, Ohio]]. He pursued a career in law, becoming a respected attorney and judge in his community. McCook was a man of strong convictions and instilled a deep sense of patriotism and duty in his large family.
Civil War Service: Despite being in his early sixties at the outbreak of the Civil War, Daniel McCook, along with many of his sons and nephews, answered President [[Abraham Lincoln]]'s call for volunteers. He was commissioned as a colonel in the [[Union Army]] and initially served as a paymaster. His primary historical significance stems from the extraordinary military service of his family members. His sons included Major General [[Alexander McDowell McCook]], Major General [[Robert Latimer McCook]], Brigadier General [[Daniel McCook Jr.]], and others who held significant commands.
Death and Legacy: Colonel Daniel McCook's life tragically ended on July 21, 1863. While visiting his son, Major General Alexander McDowell McCook, near the site of the Battle of [[Kennesaw Mountain]] in [[Georgia]], he was shot by Confederate guerrillas (often referred to as bushwhackers) while scouting ahead of his son's division. He became one of the oldest Union officers to be killed in action during the war.
The "Fighting McCooks" family became legendary for their unparalleled commitment and sacrifice. Out of the fifteen family members who served as officers, three — Daniel McCook, his son Major General Robert Latimer McCook, and his son Lieutenant Colonel George Wythe McCook (who died of war-related injuries after the war) — perished or succumbed to injuries directly related to their service. The family's dedication symbolized the profound personal sacrifices made by countless families during the American Civil War.
